I agree that, overall, the big problem here is lack of buying interest - so few people know this stock even exists. But as the end of the day comes, the sellers are busy distributing their shares at whatever price they can get instead of waiting till tomorrow -- like they have a sales quota to meet.
I've been surprised that we haven't seen Form 4s for sales. None of the insiders or 10% holders are selling. Trading is so light that distribution by minor holders depresses the price.
The greatest annoyance is that any market downturn will send ENH down from this depressed level, before it can raise itself to a fairer value.
